Yes. They are extremely reliable (Even my Nissans 2007 G35S and 2010 M35X are also extremely reliable so far!!!)
In addition, the recent Lexus are not only reliable, comfortable, quiet... They are also FUN!!!
PS: This morning I just did an aggressive downshift on my 2017 GSF to overtake a slow car... At that time my tires were cold and the weather was rainy... But, my GSF's rear tires only skidded a little bit and felt extremely well controlled and stable...(Much more controllable and stable than my son's G35S PSS10) I think its torque vectoring differential is REALLY good!!!
